C# program to check whether a number is Armstrong or not

Armstrong :

Also known as narcissistic numbers, Armstrong numbers are the sum of their own digits to the power of the number of digits. As that is a slightly brief wording, let me give an example: 153 = 1³ + 5³ + 3³ Each digit is raised to the power three because 153 has three digits.

SOURCE CODE :

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace palindrome

{

    class pali

    {

        public void palindrome()

        {

         int n, num, rev = 0, dig;

    

    

     Console.WriteLine("ENTER A NUMBER...: ");

     num = int.Parse(Console.ReadLine());

    

            n = num;

     while(num>0)

     {

          dig = num % 10;

          rev = rev * 10 + dig;

          num = num / 10;

     }

     if (n == rev)

          Console.WriteLine(" GIVEN NUMBER IS A PALINDROME");

     else

           Console.WriteLine(" GIVEN NUMBER NOT A PALINDROME");

     Console.Read();

        }

    }

    class Program

    {

        static void Main(string[] args)

        {

            pali p = new pali();

            p.palindrome();

        }

    }

}

OUTPUT:

ENTER A NUMBER

1231

 GIVEN NUMBER NOT A PALINDROME
